To all whom it may concern:

Be it known that I, DAVID WILLIAMS, a citizen of the United States of America, residing at South New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvenients in Machines for Polishing, Cleansing, and Rolling Sheets or Plates of Tin, of which the following is a specification, reference being had therein to the accompa nying drawing.

This invention relates to a machine for polishing, cleansing and rolling sheets or plates of tin, and the invention has for its object to provide a novel machine for successfully operating upon a sheet of metal or tin to cleanse the surface thereof of impurities or foreign matter that may adhere to the sheets of metal.

My invention aims to provide a machine particularly designed for cleansing, polishing and rolling sheets of tin plate as they are rapidly passed through the machine.

The machine is intended as a labor saving device, and owing to the simplicity of construction -entering into the same, the cleansing, olishing and rolling of a sheet of metal can e expeditiously and economically performed.

I have illustrated in the accompanying drawings, the preferred embodiment of my invention, and I desire it toy be understood that the same are susceptible to structural changes without departing from the scope of the invention.

Reference will now be had wherein,

Figure 1 is a View of one end of the Inachine, Fig. 2 a view of the opposite end thereof, Fig. 3 a longitudinal sectional view of the machine, and Fig. 4 is a cross sectional view thereof.

In the drawings, 1 designates an elevated plate or platform for my improved machine, and in some instances these plates can represent the floor of a building through which sheets or plates of tin can be fed into the machine, the plate 1 being provided with an opening 2 for this purpose. Upon the plate l, I construct two housings 3 and 4, having end walls 4a and 4b, and inclined sides 5 and 5a supporting hinged lids and 7, through the medium of which easy access is had to the interior of said housings. The sides 5*l to the drawings,

are provided with hinged lids 5b, whereby .easy access can be had to the interior of the housings. The housing 4 is su ported above the housing 3, and is divided t ierefrom by a horizontal partition S having an elongated slot 9 and a plurality of openings 10, upon each side of said slot, these openings being normally closed by slides 11 provided with openings 12 adapted to register with the openings 10. The slides 11 extend through the end walls 4LL and are Inanually manipulated, whereby the admission of the contents of the housing 4 into the housing 3 can be easily regulated. y

The housing 3 is also provided with a horizontal partition 12 having an elongated slot 14 vertically alining with the slot 9 of the partition S. The partition 12lL has a plurality of openings 15 normally closed by slides 16 corres onding in construction to the slides 11 of t e partition 8.

Journaled in the end walls 4iL and 4b of the housings 3 and 4 are a plurality of longitudinally disposed feed rolls 17, 18 and 19, the feed rolls 17 and 18 being' located in the housing 3, while the feed rolls 19 are located in close proximity to the hinged lids 7 of the housing 4. The rolls 17 to 19 inclusive are arranged in vertical alinement for feeding sheets or plates through the housings, and are provided with guards 18u and shields 19u. The rolls 17 are cleaned by brushes 17L carried by partition 12a of the housing 3.

Arranged intermediate the sets of feed rolls 17 to 19 inclusive are vertically disposed wire guides 20, these guides being supported from the end walls 4a and 4lo of the housings 3 and 4 by longitudinally disposed wires 21, suitably spaced to provide a rigid guide structure for sheets or plates of metal passing through the machine.

Between the sets of rolls 17, 18 and 19, are arranged sets of guide rollers 22, these rollers being journaled in the end walls 4u and 4b of the housings, and besides serving as guides for sheets or plates of metal, said rollers helping to feed the sheets or plates of metal from one set of rolls to the next set.

Journaled in the end walls 4l and 4b of the housings 3 and 4 are two sets of shafts 23 and 24 carrying hubs 25 within the housings, which are provided with radially disposed blades 26, said blades being notched as at 27, to clear the vertically disposed guide wires l 20. The tin plates passing upwardly'through the machine, are scraped to remove grease and such foreign rnatter that may adhere to the plates or sheets of tin.

In the housings 4 and 3 I place saw-dust orsimilar abrading and absorbing material, this saw-dust or material contacting with the sheets or plates of tin passing through the machine and agitating the same sufficiently to cleanse the sheets and at the same time absorb liquid or moisture that might adhere to the sheets or plates.

To maintain the contents of the housing 3 in a condition conducive to produce good results, I arrange two steam chests 28 upon the side walls 5 of the housing 3, these steam chests having steam supply pipes 29 with valves 30 and exhaust pipes 31.

The ends of the rolls and rollers protruding from the end wall 4b of the housings 3 and 4 are provided with sprocket wheels 32 and 33, a sprocket chain 34 passing upwardly over the sprocket wheel 32, this chain being suitably driven, and the tension of the same Y regulated by idlers 35 and 36, the latter being journaled in an upright 37 carried by the end wall 4D of the machine.

The shafts 23 and 24 protruding from the end wall 4ZL of the machine are provided with sprocket wheels 38 and 39, a sprocket chain '40 passing upwardly over the sprocket wheels 38 and downwardly over the sprocket wheels 39. This chain as well as the chain 34 is suitably driven and the tension of the same controlled by idlers 41.

It is thought that the operation of my improved machine will be understood without further description, and I reserve the right to make such structural changes in the machine as are permissible by the appended claims.

Having now described my invention, what I claim as new, is

1. A machine of the type described consisting of superposed housings, each of said housings having inclined sides and hinged doors, a horizontally-extending slotted partition arranged in each of the housings and provided with a plurality of openings, slides for regulating the passagevof abrading material from one of the housings to the other and for controlling the discharge of the abrading material from one housing, vertically alining feed rolls journaled in said housings, guide l rollers arranged between said feed rolls,

shafts journaled in the housings, bladed hubs carried by the shafts for cleansing the plates passing between the rolls and rollers, and sprocket chains arranged at the ends of the housings for rotating the shafts, rolls and rollers.

2. A machine of the type described consisting of superposed housings, each of said housings having inclined sides and hinged doors, a horizontally-extending slotted partition arranged in each of the housings and provided witha plurality of openings, slides for regulating the passage of abrading material from one of the housings to the other and for controlling the discharge of the abrading material from one housing, vertically-alining feed rolls journaled in said housings, guide rollers arranged between said feed rolls, shafts journaled in the housings, bladed hubs carried by the shafts for cleansing the plates passing between the rolls and rollers, sprocket chains arranged at the ends of the housings for rotating the shafts, rolls and rollers, and steam chests carried by the sides of one of sail housings for heating the abrading materia In testimony whereof I affix my signature in the presence of two witnesses.
